In addition to providing protection to the print heads, the head
carriage cover helps to keep the head carriage and printing
table clean during printing.
While the head carriage moves rapidly backwards and
forwards along the length of the printer, any contact with the
metal frame (and consequently the magnetic microswitch
stop mechanism), causes all motion to stop immediately.
The Head Carriage Emergency Stop Mechanism is fully
operational in both directions - whether the carriage is moving
from left to right, or vice versa. This prevents injury to the
operator caused by accidental contact with moving parts and
eliminates the risk of any possible obstruction caused by
hands or fingers, clothing, or other foreign objects.
12
note
In the event that the Head Carriage Emergency Stop mechanism
has been activated, a simple procedure is required to re-start
head carriage movement (via the user interface) and return the
carriage to the Home position, ready to resume printing. This is
described later in this manual, and also in the Scitex Vision
Grandjet Classic Care & Maintenance Guide.
Main Emergency Stop Buttons
The system is equipped with two Main Emergency Stop
buttons which are clearly marked and located one at each
end of the printer, on the left and right sides of the main
frame, as shown in Figure 11 below.
These buttons operate manually and when pressed,
electrical power to all motors is disconnected and air is
purged from the pneumatic system. The pressure shaft
at the rear of the printer drops down instantaneously
and all movement ceases.

System Overview
Overview of System Components
The Grandjet Classic printer system is configured in three
main modules, as outlined below.
• Printing Module - comprises ink system components
and accessories and includes: print head assembly, head
carriage, and main and secondary ink tanks. In addition,
night covers (supplied with the system) are used to
protect the print heads when the printer is not in use.
• Mechanical Module - components that control head
carriage movement, and motor-driven axles that carry
and collect substrate - see Table 2.
Table 2. System Component Identification
Component

X-axle
Enables the print head carriage to move
smoothly from left to right, and vice versa.
Y-axle
A powerful drive mechanism designed to
optimize stepping and assure smooth
forward movement of the media.
Determines the media advance rate.
Z-axle
Exerts tension on the substrate (keeping it
straight and wrinkle-free).
• Software and Controller Module - components that
provide complete operator control at all stages of print
production, via a clear, easy-to-understand graphic
user interface.
26
Shear-mode Piezoelectric Technology
Shear-mode Piezoelectric Technology
Grandjet Classic printers utilize shear-mode Piezoelectric
Technology (PZT). The shear-mode print heads use an
electrical field perpendicular to polarization of the PZT driver.
Within each print head, an electrical charge causes a
shearing action in the distortion of the PZT piezoplates
against the ink, resulting in its ejection from the print head
nozzles in fine, uniform jets. This process makes it possible
to achieve a tightly packed assembly of many jets, depositing
consistently-sized ink droplets (drop-on-demand [DOD]),
resulting in clear, high-quality printed images.

In using this advanced Piezoelectric technology, the Grandjet
Classic print heads are capable of operating at high speeds,
while maintaining superior jet uniformity. Moreover, their
precise positioning within the head carriage ensures
exceptional print quality and consistently dependable
results.

System Overview
Media Handling and Quality Control
Suitable for use with a vast range of substrate types (paper,
canvas, mesh, PVC, Tyvek, self-adhesive vinyls, fabric, carpet,
and more), the Grandjet Classic printer provides the ultimate
solution for virtually any super wide-format print job. In
addition, Scitex Vision Ltd. through Scitex Printer’s World
(SPW), offers a wide range of media that has been tested and
specially adapted for use with the Grandjet Classic printer.
(For advice and further details, contact Scitex Vision Ltd.).
The system flexibility enables you to add new media types to
the Media List and save them together with their pre-defined
printing parameters, to be used as and when required. This
saves considerable time and enhances production workflow.
reference
reference
For details, see Adding Substrate to the Media List on page 73.
The Grandjet Classic printer is supplied with a set of
substrate roll holders, comprising a hollow metal tube and a
pair of composite plastic roll protectors. These are used to
suspend the substrate roll on the media roll supports, and
also serve to protect the edges of the media. See the
illustration in Figure 72 on page 125.
When loading the printer, the required substrate is mounted
into roll holders and then placed on a pair of media roll
supports. These are positioned at the front of the printer, and
clamped onto the aluminium main frame base that runs the
full length of the printing table - see Figure 76 on page 128.
Advanced media handling capabilities contribute significantly
to the superior output results achievable. In addition, system
flexibility of the system allows for the use of substrates
narrower than the maximum printing width (in which case,
the head carriage travels only the width of the loaded media
and not the entire length of the printing table).
30
Print Mode Options
In meeting an enormous variety of general and special
printing requirements, the Grandjet Classic printer offers a
choice of different Print Mode options - as shown below.

note
The system also has a 1 Pass mode (with maximum ink
coverage of 100%), which is used mainly for testing purposes.
Selection of the most suitable print mode will depend upon
various factors, such as the specific print job application, the
required viewing distance, and the media type.
While the 2-Pass mode is ideal for printing billboards since
these are viewed from afar, the 3 and 4 Pass modes are
generally suitable for applications such as banners, which
are printed for medium- to long-distance viewing. However,
images demanding close-distance viewing (for example,
exhibition graphics or Point-of-Purchase signs) will require
use of the 6 and 8 Pass modes (see Table 4).

33
System Overview
• CMYK TIFF-BMP: PC format, up to 4 separate channels
(one per separation), maximum resolution of 370 dpi,
1 bit per cell.
A wide range of input options is available, enabling you to
exercise great dexterity when selecting the exact input
resolution for the required print output, as follows:
• For close-viewing, indoor applications (such as,
exhibition graphics or Point-of-Purchase signs) in BMP
format, 8-Pass mode, and resolutions of 185 dpi or
370 dpi, may be required.
• For applications that are less demanding (such as,
banners to be viewed from a medium-long distance)
for image files in TIFF format, 3-Pass mode, with a
lower resolution (for example, 23.125 dpi), would be
appropriate.
34
Ink System and Color Controls
The Grandjet Classic printer has two types of ink containers,
as described below. The ink system is controlled electrically
and pneumatically; while the printer is in operation and the ink
valve is open, ink flows under constant pressure through the
ink system.
•
Main Ink Tanks
Four large tanks each containing one color ink (black,
yellow, magenta, or cyan) are located at the base (rear) of
the printer (see Figure 15).
Figure 15. Main Ink Tanks
•
Secondary Ink Tanks
Four small secondary ink tanks are mounted on the head
carriage, each of which has three internal compartments
(chambers) vertically positioned at staggered heights, as
shown in Figure 16.
Chamber 1
Chamber 2
Chamber 3
Figure 16. Secondary Ink Tank - Cross Section
35
System Overview
When secondary ink tank filling commences, the first
compartment (Chamber 1) fills with ink until the ink level
reaches the point at which it is level with a hole in the
side of the chamber, from where it flows into the second
compartment. Similarly, when Chamber 2 is sufficiently
full, the ink flows into the third compartment. When
filling of this chamber (which is fitted with a buoy - see
Figure 17) is complete, an ink sensor (located on the
secondary tank) senses that all three chambers are full,
and ink filling then stops automatically.

Chamber 3
Ink Flow Direction
Figure 17. Secondary Ink Tank
Each secondary tank is fed by one main ink tank and
accordingly contains ink of a specific color - black,
yellow, magenta, or cyan.
In the same way in which the print heads are mounted
on the head carriage in four color groups (six heads per
row), the secondary ink tanks are similarly configured
according to color, as shown in Figure 18.

Advanced Formula Inks
The GR100 Supreme and Rainbow inks recommended for
use with the Grandjet Classic printer have undergone
extensive research and development in Scitex Vision Ltd.
laboratories. Tested under rigorous conditions, these
advanced-formula inks have proved consistently reliable.
Not only do they produce superior quality results, but they
have also demonstrated greater outdoor durability and
resistance to heat, moisture, and ultra-violet rays. Moreover,
these inks are water and abrasion resistant, and in most
applications they eliminate the need for clear coating or
lamination of the printed media.
The unique formulation of fast-drying solvent-based inks,
combined with special additives, results in stronger and
faster ejection of larger-sized ink drops from the print heads.
This has a dramatic effect on text clarity and sharpness, and
also enables the Grandjet Classic printer to deliver print
quality with an exceptional color gamut and very high optical
density. The GR100 Supreme and Rainbow inks produce
strong results, giving an overall print output with a glossy
appearance, vivid reds of striking quality, and true-to-life
skin tones.
When using GR100 Supreme and Rainbow inks with the
Grandjet Classic printer, significantly lower quantities of ink
are required. For example, for self-adhesive vinyls the
recommended ink coverage is 200-250%; for Flex-face
banners it is only 250-350%. This results in a significant
reduction in printing speeds and has a positive effect on
print production costs.
CAUTION
Use only inks and solvents approved by Scitex Vision Ltd.

Using Color Look-Up Tables (LUTs) for TIFF Files
Due to varying results obtained from printing on different
media, sometimes it is necessary to perform color correction
by adjusting the input/output ratio for each of the four
colors.
These adjustments are made on the color curves of Look-Up
Tables. The color correction procedure can be performed
only for TIFF files, and not for TIFF-BMP files.
note
It is recommended to perform color correction for TIFF-BMP
files on a dedicated Scitex PPS or RIP server.
From the Edit dialog box, click Edit next to the LUT field to
change color curves.

WARNING
Do not attempt to make changes to the Y-Advance value since this may result in
image distortion!
The Y-Advance is pre-set in the factory and it is recommended that only an
authorized Scitex Vision Ltd. FSE make any amendments required.
5. Click Length corr. (length correction) in order to correct
the image height distortion, if required.
note
An experienced operator will quickly become familiar with
correction percentages.
For example, for a correction of a 1% height distortion, add a
length correction of the same value.
6. Set the Delay value required (in milliseconds) to pause
the print head carriage between printing each pass (1000
ms = 1 second).
tip
If the Delay value is set at 0, passes will print one after the other
with no delay (causing the next pass to print on wet ink).
Increase the Delay value for media that requires a longer drying
time.
Setting the Delay value may reduce printing speed marginally,
but ensures that the pass is always printed on dry ink, whereby
color consistency is maintained.
7. Set the required Media distance value.
74
Control Area
The ability to set this parameter is only relevant when
saving the settings. (Changing the value alone has no
effect).
Generally, the lesser the distance, the more accurate the
print. However, since different substrates vary in
thickness, this should be considered when setting a value.
8. Under the General settings, proceed as follows:
• For normal printing, select Use Y-Delay.
note
During normal printing the Use Y-delay check box should always
be activated to ensure that all four print head colors are not
printed simultaneously while the media is advancing in a vertical
direction over the printing table.
For example, with Y-Delay activated, printing of the first line of
magenta will not commence until the first line of cyan has been
printed. Similarly, yellow "waits" for the first line of both
preceding colors to finish, while black is delayed for all three.
In this way, color registration is maintained for the entire print
run.
• When aligning the print heads for test purposes,
deselect Use Y-Delay so that all four print head colors
print simultaneously.
9. Perform the Media Registration & Color Alignment Test
(see the instructions on page 133) to check the print
alignment and color registration on the media.

Configure - Color Alignment
In order to accurately check media registration and color
alignment, a specially-designed Registration Test file is
supplied with the Grandjet Classic printer.
After printing this file, any adjustments required are easily
made using the software (under the Setting tab in the
Configuration dialog box). The test file checks the following:
1. Left/Right Adjustment – used to align each of the
4 print head colors (cyan, magenta, yellow, and black) in
relation to the timing of head carriage movement (left-toright and right-to-left).
Cyan is the master color, to which alignment of all other
colors is referenced. For example, making an adjustment
to cyan, the same change will automatically be made to
the other three colors: magenta, yellow, and black.
With the aid of the printed test file, adjustments may be made
(in accordance with the test results) by changing the unit
value displayed in the Cyan input field (labelled C) under the
X-Left & Right column of the Configuration dialog box:
In this way, precise alignment of all
print heads of the same color will be
achieved (cyan-to-cyan, magenta-tomagenta, etc.) resulting in clear
printing of sharp colors.
Refer to Adjusting the Print Head
Color Alignment - X Left & Right on
page 79.
2. X/Y Color Alignment – used to align all print heads (for
each of the 4 colors), on both the X- and Y- axes. This
check ensures that successive colors are printed in exact
alignment with previous colors (cyan-magenta-yellowblack to cyan-magenta-yellow-black).
77
Cyan is the master color, to which alignment of all other
colors is referenced. For example, making an adjustment
to cyan, the same change will automatically be made to
the other three colors: magenta, yellow, and black.
With the aid of the printed test file, adjustments may be
made (in accordance with the test results) by changing the
unit value displayed in the Cyan input field (labelled C)
under the X-Offset column of the Configuration dialog box:

System Start-up from Idle Mode
During normal use, there may be short periods of time when
the Grandjet Classic printer is not actually in the process of
a print run, but is standing in Idle mode. For example, prior
to commencing a new job, while loading substrate, or during
care and maintenance procedures.
Whenever the printer is in Idle mode, electrical and pneumatic
power to the system is operational and the head carriage is
parked in the home position (to the left of the printing table and
in front of the cleaning station). In this state, the night covers
are not currently in use and ink is spraying continuously from
the print heads to maintain nozzle patency.
When starting the Grandjet Classic printer from Idle mode,
certain minimal procedures are required as described below.
!
Starting up the Printer from Idle Mode
1. Check that the print head nozzles are spraying correctly
by performing Step 3 and Step 4 of the Cleaning the Print
Heads procedure previously described (see page 108).
If required, clean the print heads (Step 1 and Step 2 - see
page 106).
2. Check that all the main ink tanks are full and, if necessary,
follow the procedure for Filling the Main Ink Tanks on page
120.
3. Make sure the Grandjet Classic printer has been loaded
correctly with the required substrate - see Loading the
Substrate on page 122.
4. Set the required printing parameters - see Editing
Printing Parameters on page 59.
119
Filling the Main Ink Tanks
!
Filling the Main Ink Tanks
tip
When performing this procedure, use of a funnel is recommended.
Once filled, the main ink tanks may be re-filled again as
necessary, while printing is in progress.
1. Close all air pressure hoses connected to the main ink
tanks you wish to fill. (Refilling requirements are
established by visual inspection).
2. Release the excess air from the first main tank, by
turning the blue tap located on the side.
3. Unscrew the black cap and tubing from the tank.
4. With the main tank standing firmly, carefully refill it with
ink of the correct color (as marked on the outside of the
tank) making sure you avoid any splashing - Figure 67.
Figure 67.Filling the Main Ink Tank
120
5. When the ink tank contains no more than 4 liters, stop
filling; replace the screw cap on the ink bottle and tighten
firmly.
CAUTION
The maximum capacity of each main ink tank is 4 liters; it is recommended
that each tank should contain no less than 2 liters. If there is insufficient ink
in the main ink tanks, the print heads may be exposed to long-term damage!
Screw the black cap (and its corresponding tubing) into
place on the main ink tank, and tighten firmly as shown
in Figure 68.
Figure 68. Tightening the Main Ink Tank Cap
6. Repeat Step 1 through Step 5 for any other tanks that
require refilling, using ink of the appropriate color.
7. Check that all caps are tightly closed, then open the
corresponding air pressure tap on each of the main tanks.
8. Check the ink tank air pressure gauge reading (see
Figure 69) (situated behind the computer, at the base of
the printer), and if necessary adjust to 0.2 BAR.
Figure 69. Air Pressure Gauge - Main Tanks
121
Loading the Substrate
The Grandjet Classic printer has a maximum printing width
of 3.2 m (10.6 ft) and can accommodate an extensive variety
of substrate types. With virtually no limit to the length of
substrate which may be used, suitable materials include:
paper, canvas, mesh, PVC, Tyvek, self-adhesive vinyls, fabric,
carpet, and more.
The flexibility of the system facilitates the use of substrates
narrower than the maximum printing width (in which case,
the head carriage travels only the width of the loaded media
and not the entire length of the printing table).
Loading the system with substrate is a simple procedure; the
required media roll is loaded into a set of substrate roll
holders (see note below) and mounted onto a pair of media
supports clamped to the front of the printer (see Figure 72).
The end of the roll is then threaded around a series of axles
and guide shafts, over the printing table, and finally taped
firmly into position on the Z-axle at the rear.
Figure 70. Grandjet Classic Printer Loaded with Media
note
The Grandjet Classic printer is supplied with one set of
Substrate Roll Holders, as standard. This comprises one hollow
metal tube (3.2m in length) and a pair of plastic roll protectors.
122
!
1. Working from the front of the printer, position each of the
two media supports at an appropriate distance apart
(determined by the length of the media roll you intend to
load). Attach each support arm to the printer aluminium
base frame, using the locking clamps provided - see
Figure 71.
Cradle
Locking Clamp
Adjustable Foot
Figure 71. Media Support Attached to Aluminium Frame
2. Using a hand-held spirit level, check that each support is
standing level and if necessary, make any adjustments
required by turning the screw to raise or lower either one
or both of the adjustable feet at the base of the support see Figure 71.
3. With the left and right media supports standing level with
the printer, tighten the locking screw on each clamp (refer
to Figure 71) to lock the supports firmly into position on
the lower cross beam, and prevent lateral movement.
123
4. Mount the required media roll into a set of substrate roll
holders by inserting the metal tube through the media
roll core and attaching a plastic protector at either end.
tip
Make sure the roll protectors are fitted flush with the edge of
the media roll. These will act as buffers and prevent any tearing
of the media.
5. Using a minimum of two persons (or a lifting device if
necessary) carefully load the mounted roll onto the media
supports, centering it lengthwise and resting each end of
the central tube into the cradle at the top of each media
support - see Figure 72.
tip
note
Carefully position the roll centrally, with the end of the media
pointing upwards - see note below.
Although many different types of substrates are available, there is
no one standard way in which they are wound onto the inner core
when supplied from the factory. Some are supplied with the
media surface to be printed on the inside of the roll while others
are the opposite - with the surface to be printed on the outside.
For this reason, when loading a substrate roll onto the Grandjet
Classic printer there are two factors which should be taken into
consideration:
a) the way in which the roll is wound, and
b) how the roll is lying when placed on the media supports

At this stage, applying slight tension to the Z-axle is
recommended as this will help to hold the substrate
securely while taping it into position. This is achieved via
the Grandjet Classic main screen by clicking the Material icon to
access the Material Control Dialog box - see Figure 75.
Type over the figure currently displayed in the Z-tension field
and amend it accordingly (the appropriate value will be between
10 and 40, depending on the material type).
Click the On button. Slight tension will be applied to the
Z-axle, without the shaft actually moving.

between the printer side frame (on the left) and the left
edge of the substrate roll on the guide shaft (A), as shown
in Figure 77.
Figure 77. Measuring the Distance to the Edge of the Media Roll
129
t ip
When measuring the distance, it is helpful to use a small piece
of adhesive tape to temporarily secure the roll in position on the
Z-shaft preventing movement of the substrate. This must be
removed once final measuring is complete.
12. Standing at the rear of the printer, measure the distance
between the printer side frame (on the right) and the right
edge of the substrate roll on the Y-axle (see Figure 74),
making sure that this is exactly the same as that
measured in Step 11. If necessary, adjust the position of
the substrate as required.
13. Using adhesive tape, attach the end of the substrate roll
to the Z-axle, working outwards from the centre of the
substrate, and pulling firmly to prevent wrinkling.
14. Activate the piston and pressure shaft to exert pressure
on the Y-axle by pressing the up arrow
on the
piston control switch - refer to Figure 73 on page 126.
The pressure shaft rises and exerts pressure on the
Y-axle.

Set the appropriate Z-Tension value (the required
amount of tension to be exerted by the Z-axle - up to a
maximum of 120) by typing over the figure currently
displayed and clicking On.
note
The recommended Z-tension values are between 70 and 100 for
vinyl and papers, and up to 120 for substrates that are less
elastic.

The Grandjet Classic printer is now loaded with substrate,
and the Z-tension is set. You are ready to adjust the
substrate advance settings - refer to the next page.
tip
Whenever loading the Grandjet Classic printer with a new type
of substrate (that has not been used previously), you may add
the media to the Media List and save the relevant printing
settings in the system for easy access in the future.
For details, see Adding New Substrates to the Media List on the
next page.
Setting the Substrate Advance
With the Grandjet Classic printer loaded with the required
substrate, you are ready to set the required Material
Control parameters, This is necessary to govern the amount
by which the substrate will move forwards or backwards.
reference

For step-by-step instructions, see Advancing and Retarding the
Substrate on page 88.
131
Adding New Substrates to the Media List
The Grandjet Classic printer provides the facility to add new
substrates to the Media List, and save their corresponding
printing settings in the system. This saves time, and enables
you to build up a readily-accessible ‘library’ of substrates together with their pre-defined printing parameters - for
future use. Thereafter, selection of the required substrate
from the Media List, provides instant access to automatically
predefined parameters, such as tension, substrate advance
rate, amount of ink, as well as printing mode, speed, and
resolution.
When adding a new substrate type to the system, values used
for “fine tuning” and adjustment of the left/right head carriage
movement - as well as X/Y color alignment settings - may also
be saved with the new file. Moreover, if you wish to use the
same media type under different conditions (for example,
printing at a faster [or slower] speed), a new file (with a new
name and the relevant settings) can be added and saved in
the Media List.

Preparing Files for Grandjet Classic printer
Suitable Graphic Image Types
Two graphic image types are suitable for use with the
Grandjet Classic printer - TIFF and TIFF-BMP; these are the
only formats which may be used. Files may be prepared as
IBM-compatible, they should not be compressed, and their
color composition must be CMYK.
A graphic image that has been saved as a PS or EPS file may
also be used, but only after it has been converted to TIFF or
TIFF-BMP format, using Raster Image Processing (RIP)
software. The conversion process creates a file capable of
being read by the Grandjet Classic computer.
By their very nature, graphic files tend to be ‘heavy’ and
therefore require considerable computer memory and disk
space. For this reason, the dedicated Grandjet Classic computer
must not be used for actually creating graphic images. These
should be prepared using another computer, after which the
saved files may be imported by the Grandjet Classic computer,
from an external source (for example, a network or CD).
Before creating graphic files, an understanding of a few basic
concepts may be helpful. When a graphic image is reproduced
by the Grandjet Classic printer, the printed picture comprises
a multitude of tiny dots - referred to as halftones. In general,
the closer the dots are in proximity to each other, the finer the
print quality. Although many factors (for example, substrate
type) determine the final print quality, the screen angles at
which halftones are created is significant. If they are not
printed at the correct angle, the picture quality may be spoiled
by an undesirable Miorè effect.
note
Miorè effect is the term used to describe the unattractive
mottled patterns occurring when halftones are not printed at
the correct angle.
150
File Preparation Criteria
File Preparation Criteria
In order to prepare a file from any graphic application
(vectors file), you will first need to ensure that the following
criteria have been met:
• Pictures should have a minimum resolution of 23.125
ppi at the actual print size.
For example: if you are using an A4-sized file, and use a
300 ppi resolution image, bear in mind that it may be
enlarged up to 13 times without losing image quality.
However, if you wish to enlarge the image greater than
this, make sure the image was scanned at more than
300 ppi. Alternatively, enlarge the image at a smaller
scale.
• When exporting to an EPS file, you must make sure
that all text was converted to path, or that it is
included in the EPS (providing the software allows
this).
• When printing to a PS file, do not forget to activate
Include All fonts, when closing the file. Use the
PSPrinter chooser extension.

Creating a PS File for Ripping
Once a graphic image has been created in any graphics
program (for example, Adobe Illustrator, QuarkXPress,
or FreeHand), the file must be made ready for printing. It is
best to save it as a PS file. This is preferable to EPS format,
particularly when the image includes text, as you need to
preserve the original fonts, and prevent the RIP program from
replacing them.
